When you walk in, you first see the ceremonial gate, the plaque hanging on the "guardian state". The main building of the most striking building in Shuri Castle is a wooden structure with a distinctive style of croquet and a combination. The characteristics of traditional Chinese and Japanese architecture are grand and colorful.
There is now a very Japanese-style tea room in Shuri Castle, where you can enjoy an Okinawa-style refreshment and a Japanese-style courtyard for only 300 yen per person.
PS: You can enjoy the discount for the Shuri City ticket with the one-day ticket for Okinawa Metro. The price after the discount is 660 yen. There is a subway to reach Shuri Castle, but the subway needs to change to a bus, otherwise it will take 15 minutes to walk from the subway.
